Do the surfaces look correct in these regions? You might post some screenshots of subjects who have a big difference between 5.1 and 5.2 with the 5.1 and 5.2 white and pial surfaces on volume slices that highlight the difference. Without this kind of info, its hard to know which was more correct, 5.1 or 5.2.
